Phospho-Src (Tyr529) Antibody

About the Target

Src is a non-receptor tyrosine kinase involved in various cellular processes, including growth, differentiation, and survival. Structurally, Src comprises several domains: an N-terminal myristoylation site for membrane association, SH3 and SH2 domains for protein-protein interactions, a tyrosine kinase domain responsible for its catalytic activity, and a C-terminal regulatory region containing Tyr529. Depending on the literature source, SRC may also be discussed as Phospho-Src (Tyr529).

Reported cellular context includes cell junction, cell membrane, cytoplasm, and cytoskeleton, which can matter when signal is compared across treatments or changing cell states. Following SRC across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

SRC is commonly interpreted in the context of cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell junction, cell membrane, and cytoplasm, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between cell junction, cell membrane, and cytoplasm across matched conditions
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation
• differences between total target abundance and site-specific regulation when modified forms are compared
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for SRC. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in SRC reflect biology rather than handling. When interpreting SRC, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep SRC trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
